3) Use a pair of pliers to bend up the metal top cap of the mini USB connector on the other end of the cable. There's a kind of "zig-zag" line where the two pieces of metal meet up, and all you have to do is bend them up slightly to either side to expose the copper pins. 4) Take a soldering iron and apply a tiny smear of solder between the exposed pins 4 and 5 near the back; if the solder beads up too much just scrape it down a bit with either the soldering iron or a small file so that it's fairly flat. 5) Bend the metal top cap back down into original position.
